Fear is a very powerful emotion. Fear directly triggers the limbic system of the brain, which raises our heart rate, the level of adrenaline in the blood and depending on the situation, it causes us to freeze, fight or flight. No other emotion has that strong a connection with the body.
Fear is so powerful that it stop us from thinking clearly, it overrides our rational brain. It takes a lot of effort to overcome fear and tell ourselves that there is nothing to be afraid of.

Next they start to envision their options and almost talking to themselves. The rational mind is trying to override the limbic system. Would you jump?
